The International HYDROTRANSPORT Conference series is unique in its long-standing history of bringing together operators, designers and researchers to discuss important themes related to the transport and handling of solid-liquid mixtures.

The Conference has been the showcase for many innovations in the application of hydrotransport technology. The 22nd International Conference on Hydrotransport focused heavily on many of the most important applications, including:

• Water usage, and environmental implications of mining, mineral processing, oil and gas production and pipeline integrity.
• The use of alternative sources of energy to supplant, or at least complement, the use of hydrocarbon resources.
• Development and testing of new materials that provide improved resistance to wear and corrosion.
• Advancing and deploying powerful computational models.

Presentation: “The successive development of multi-component modelling for slurry pipeline friction losses”

Abstract: A brief review is given of some various steps behind the present 4-Component Model with reference to recent literature where the calculation procedures are described in detail. The presentation here focuses on wide particle size distributions relevant to my interest in co-disposal of crushed rock and tailings. In addition, hydraulic hoisting from underground mines and the effect of solids on the performance of centrifugal pumps are briefly covered.

About the Award Winner: Prof. Sellgren was formerly head of the Division of Water Resources Engineering at Luleå University of Technology in Sweden. He holds a BS in Mathematics from the University of Gothenburg, and a MS in Civil Engineering from Chalmers University of Technology, Gothenburg, where he also holds a PhD in hydraulics. In the early 1980s, he worked as a research associate at the Mining and Minerals Resources Research Institute at the University of Arizona, U.S.A. He has since accumulated over 40 years of international experience in the research, development and design of various slurry pumping systems, has published numerous academic papers in the field, and has contributed to the first edition of the ANSI/HI Centrifugal Slurry Pump Standard. He joined the teaching staff of the annual GIW Slurry Course in 1989, contributed to the 1st edition of the textbook, “Slurry transport using centrifugal pumps” and was a co-author in the 2nd and 3rd editions in 1996 and 2006, respectively. He has been an important co-author of the 4th (2023-) edition on many topics, but especially in the areas of centrifugal pump solids effect and pump-system interactions.

About the HYDROTRANSPORT Career Excellence Award: This award is given in recognition of a sustained career excellence. It is intended to provide recognition of outstanding and original contributions to the development, implementation, improvement, and/or understanding of hydrotransport-related technology, as well as long-term service to, and leadership within, the hydrotransport community at large.

Presentation: “Experimental Techniques and Methodologies for Multiphase Systems: A Convergence of Academic and Industrial Perspectives”

Abstract: Multiphase systems are at the core of numerous industrial processes, ranging from chemical manufacturing to energy production. The complexity of these systems, characterized by interactions between gas, liquid, and solid phases, requires advanced experimental techniques and robust methodologies to accurately capture and analyse their dynamic behaviours. The latest experimental approaches used to investigate multiphase systems, with an emphasis on bridging the gap between academic research and industrial application will be discussed. By examining case studies and emerging technologies such as high-speed imaging, velocimetry measurements, and tomographic techniques, we highlight how innovations in experimental design are enabling more precise measurements and help towards robust and validated computational modelling. Furthermore, we discuss the importance of collaborative frameworks between academia and industry, which foster the translation of theoretical insights into practical solutions. This union not only accelerates technological advancements but also ensures that experimental practices remain relevant to real-world challenges. The work aims to serve as a comprehensive reference for researchers and engineers seeking to develop or apply experimental methodologies in the field of multiphase systems.

About the Speaker: Dr. Alberini joined the University of Bologna in 2021, after five years as an Assistant Professor at the University of Birmingham. He is primarily focused on experimental characterization and modelling of chemical, biochemical and process industry equipment, with an emphasis on multiphase mixing involving non-Newtonian fluids. In 2018, he received the Young Researcher Award from the Working Party on Mixing of the European Federation of Chemical Engineering. He is also a member of the scientific committees of several international conferences (ISMIP, European Conference on Mixing, NAMF). Since 2014, he has participated in several research projects funded by EPSRC and Innovate UK (UK Council) and has been coordinator and scientific manager of a number of privately funded research projects.
